As part of the partnership between Trace De Trail and the International Trail-Running Association (ITRA), you can link your Trace de Trail and ITRA accounts. This is done from the ITRA website.
A Trace de Trail account using a Facebook connection can not be linked to your ITRA account.
Once your accounts are linked, you will have access to your ITRA space on Trace de Trail (Menu / My ITRA Space). This one shows all your tracks evaluated as well as the tracks evaluated on the ITRA account.
You can transfer the tracks of the ITRA account to your own account so that you can modify them by adding points of interest, sections, a description...
